A medical student who ran a prescription drug ring with her Brooklyn hospital resident boyfriend was sentenced on Monday to 90 days behind bars for violating her parole by stripping at a Kentucky jiggle joint — where she netted up to $2,000-a-night.

But Pauline Wiltshire, 32, will get to keep her day job – making minimum wage selling dishwashers at Sears – by serving her sentence only on weekends, according to the sentencing handed down by Brooklyn federal Judge Dora Irizarry.

Wiltshire, sporting an unflattering bob cut, a purple cardigan and matching slip-on shoes, looked far from glamorous as she sat before the judge.

The pill pusher was ripped by Irizarry for lying to her parole officer about her seedy exploits that involved crossing state lines from Ohio without approval. The judge was especially peeved because she gave Wiltshire a slap-on-the-wrist sentence of six months house arrest in April 2012 – a far cry from the recommended sentencing of 57 to 71 months.

“I gave you a substantial break,” Irizarry told Wiltshire. “At the time of sentence, you sat here sobbing about how remorseful you were about how you were going to go straight.”

But Paul Kish, Wilstshire’s attorney, claimed his client turned to stripping at the Platinum Plus nightclub in Lexington more than a year ago because she couldn’t find other work locally.

“Southern Ohio [where she is now living] is economically depressed. There is just no work there,” said Kish.

Wiltshire, who declined comment, took the Sears job three months ago.

Wiltshire pleaded guilty to selling Adderall pills via the Internet, with her boyfriend who was a resident at Methodist Hospital in Park Slope.

She received the lenient sentence partly because of steep student-loan debts and her claim that she earned less than $200 a month.
